Hey guys, Is it legal to make a AR pistol from a AR that was bought as a rifle from a FFL?

So Have a few things I want to ask. first off I just want to say your podcast is the best around I drive from Rhode Island to New York City and back five days a week and you guys really make that ride enjoyable. I discovered your show around podcast 150, I listen to you on iTunes and I am currently listening to the whole backlog, and when I’m done it’s going to suck to have to wait. So the first thing I want to ask is would you go for a scar heavy (17) or the dez tactical 308? now I know you guys are fanboys of dez and I am fond of them too, I do plan on purchasing the Dez 223 in the future but would you go scar heavy or the dez for 308? it’s pretty much going to be a range toy that eventually I want to shoot at medium to long range. If you guys can answer on your show that would be great. Second thing I wanted to ask if you could also touch upon how to get children into shooting like where do you start because I have two nephews who are 11 and 10 and I really want them to be advocates of the Second Amendment and I know it starts at a young age so how would I go about starting the process of teaching them firearm safety??? Most gun ranges don’t allow me to take them until they are 15. It would be cool if you can talk about these two questions on your show (or make it an entire episode. You could call it “for the children”) last, what is the difference between the battle box and the skirmish box and how many at each level would i receive per year because I will be definitely becoming a patreon and do you release the uncensored version on iTunes? finally the last thing I wanted to say is Aaron is easily the best panel member A-A-RON 4 life

Thank for taking the time to read this

Dear WLS,

A friend of mine keeps an M&P shield in his car all the time and since he’s in Texas and it’s summer the gun and the ammo that’s in it gets very hot. Will this eventually harm the structural integrity of the Shield’s polymer frame? Also how long will the ammo last under such conditions.
